The Cricut Hat Press with the new Cricut Heat app (required to use the product) has taken the guesswork out of making custom hats. I have used both Cricut hats and non-Cricut hat blanks with great results. The curved heat plate works amazing with the hat & the hat form ensures a well-pressed item. For sublimation or Infusible ink, it does require A LOT of the strong heat-resistant tape. And, there is a learning curve to prevent ghosting along the bottom. However, once you master that, you can make a hat in no time at all! It's been a fun product to play with!
